Topics covered in this chapter 11 Transportation in Animals and Plants:
The plant and animal transportation systems are essential for transferring nutrients and other components in different body parts. Numerous substances, including blood and oxygen in the case of animals and nutrients and fluid in the case of plants, spread out in the entire body through the transportation system. Furthermore, both plants and animals have different transportation systems. This article will talk about the transportation systems of both plants and animals.
The transportation process in animals is complicated. The system requires serious attention to learn this chapter. It transfers nutrients, oxygen and blood throughout the human body. There are different parts of the transportation process. Listed below are the various components of the transportation process in animals:
The Circulatory System in human beings plays an essential role in the transportation system. Listed below are the parts of the circulatory system:
The first component of the circulatory system is blood. Blood is the red-coloured fluid that flows throughout the body. Blood carries various components, including food, oxygen and waste. It transfers the food from the small intestine to the other parts of the body and the oxygen from the lungs to the different parts of the body. It also carries the waste for removal from the body's large intestine.
Blood has two parts-the cells and plasma. Blood cells are the parts that transfer components from one organ to another. On the other hand, plasma is the liquid part of the blood.
There are three types of blood cells in the human body. Listed below are the three types of blood cells:
Red Blood Cells: Red blood cells are blood cells that consist of haemoglobin that is red in colour. It connects the oxygen with various parts of the body. Without haemoglobin, blood cannot transfer oxygen to the other body parts. Red Blood Cells are also known as RBCs.
White Blood Cells: White Blood Cells are defensive blood cells of the body. White Blood Cells help the body fight against various illnesses and germs that enter.
Blood Platelets: Blood Cells that form clots in the body are known as Blood Platelets. These cells are responsible for curing injuries and cuts in the body by cutting the blood.
Blood Vessels are responsible for transferring blood to the other parts of the body. There are two types of blood vessels in the body- arteries and veins.
Listed below are the two kinds of blood vessels:
Arteries are blood vessels that transfer blood rich in oxygen from the heart to other body tissues. All types of arteries carry oxygen-rich blood except the pulmonary artery. The arteries are muscular and thick in size because the blood flow in the body is fast. The blood vessel has three parts- the intima, media and adventitia. The most significant type of artery is the aorta.
Veins: Veins are blood vessels that transfer blood rich in carbon dioxide from the other body tissues to the heart. Unlike arteries, veins are thin-walled. Veins also contain valves that help control the carbon dioxide induced blood flow only towards the heart.
The heart is one of the most vital organs of the body. It continuously pumps blood, supplies oxygen to the heart, and takes in carbon dioxide. It is present in the body's chest cavity, and the tip of the heat is tilted a little to the left. The heart has four parts or chambers- two atria and two ventricles. The valves present in the four chambers prevent the mixing of oxygen-rich blood and carbon dioxide-rich blood.
The walls of the heart valves consist of muscles that contract and relax. These contractions and relaxations are known as heartbeats. The heartbeats determine the condition of the heart and how well the heart is pumping blood.
The process of removing wastes from the body is known as excretion.
The entire system is known as the excretory system. The waste present in the blood is harmful to the body. Therefore, it needs an outlet to get out of the body. The excretory system enables the litter to pass out of the body. Listed below are the steps that comprise the human excretory system:
The kidney filters out the liquid waste from the blood. When the blood reaches the kidney, it contains both negative and positive substances. The kidney absorbs the positive substances and excretes all the harmful waste through urine. The kidney, therefore, acts as a filter to differentiate the particles from each other. The urine formed in the kidney transfers to the urinary bladder and then to the ureter and then passes to the urethra. An adult generally urinates 1 to 1.8 L of water in an entire day. Urine consists of 95% water, 2.5% urea and 2.5% other waste products. Like urine, sweat from the human body also contains salt and water. The sweating process keeps the body cool by eliminating all the toxins from the body.
Therefore this is the entire transportation process of nutrients, water, food and oxygen in Animals.
Transport of Substances in Plants
The excretory system in plants contains xylem and phloem. The vessels in plants are like pipes that transfer nutrients and water from the soil to the plants. The plant vessels make up the vascular tissue that moves the nutrients and water in the plant. It is known as the xylem. The vascular tissues of the xylem form a bond with each other and connect the roots of a plant to the leaves. It also simultaneously joins stems of the plant to the branches to create a proper system of transporting water and nutrients to all parts of the plant.
Leaves require food for nourishment. The vascular tissue that transports food to the entire plant is known as Phloem. The Phloem transfers the food to all parts of the plant.
Therefore this entire process is the transportation process in plants.
1. Explain the transportation system in plants.
Transportationsystems in plants include the transfer of nutrients and water. The organs involved in the process are Xylem and Phloem. They connect the soil to the plants and transfer the nutrients from the plant's roots to the plant's leaves through the vessels present in the different organs of the plant. Phloem also moves food from the soil to the leaves. The transportation process helps the plants gain nourishment, nutrition, and growth. Therefore, this is the transportation system in plants.
2. Explain the circulatory system in human beings.
The circulatory system in human beings helps in the transportation process. The method includes the heart, which takes in carbon dioxide and pumps out oxygen. The heart plays a significant role in maintaining the blood flow in the human body. The heart's valves also ensure that the blood that the heart pumps out is rich in oxygen. Two blood vessels transport the blood from the heart and the blood to the heart; they are arteries and veins. Arteries transport oxygenated blood from the heart to various body parts, while the veins transfer carbon dioxide-rich blood to the heart. Therefore, this is the circulatory system in human beings.
3. What is the excretory system in human beings?
The process through which the human body eliminates waste is known as excretion. The process and the organs involved in the process as a whole are known as the excretory system. It includes kidneys, urinary bladder, uterus, urethra. The blood contains waste that it tries to eliminate. Therefore, the kidney acts as a filter in the body. It dissolves the harmful waste and blends the suitable substances in the blood again. The toxic waste in the form of urine that contains water and salt then moves to the urinary bladder, ureter and finally to the urethra to be eliminated by the body. Sweating is another part of the excretory system. It cools the body and releases toxins.
4. What is the purpose of a transportation system in the body?
The transportation system regulates blood flow, excretes waste materials from the body and releases harmful toxins from the body. In addition, it cleanses the body and cools it down. The transportation system also transfers oxygen and nutrients to all body parts and eradicates any harmful waste. Therefore, this is the purpose of the transportation system in a body.
