Transportation in Animals
Transportation of gases, nutrients, and other essential things to different body parts, this transportation is done in the circulatory system. In this circulatory system, many organs play an important role. Some of them are explained below: –
- Blood: Â Blood is fluid that flows in vessels. It helps to transport the digested food small intestine to other organs and it carries oxygen from the lungs to cells. It also carries waste materials from different body organs to extract. Blood is made up of plasma in which different types of cells are involved some of them are explained below: –
Red Blood Cells (RBC): – RBCs are red and contain Hemoglobin. Hemoglobin binds with oxygen and transports oxygen to different cells of the body. Due to hemoglobin, our blood color is red.
White Blood Cells (WBC): White Blood cells help our body fight germs.
Platelets are another cell present in Blood. They stop the flow of blood after injury and make a clot in the injured area.
- Blood Vessels: Our body has Different blood vessel types. As we discussed above, blood flows and transports many things in our body, so it flows in a tube-like structure. In Chapter 10 Class 7 Science, we study that when we take oxygen, it enters through the nose and reaches the lungs via a pipe-like structure. So this structure is known as vessels. There are mainly two types of blood vessels in our body.
Arteries: – Arteries have oxygen-rich blood. In arteries oxygen-rich blood flows from the heart to other parts of our body. Arteries have thick walls. Arteries are divided into thin tubes at the end of tissue, these thin Tubes are called Capillaries.
Veins: – These are those vessels that carry carbon dioxide-rich blood and flow different parts of the body to the heart. Veins have thin walls.
- Heart: This is the most important part of our body. Heart pumping continues and pushes blood to different organs. The heart is the center where the oxygen-rich blood from the lungs and carbon-dioxide-rich blood from different organs come together. To avoid mixing this blood, the heart has four chambers.
Artia: – The two upper chambers of the heart are known as Artia.
Ventricles: – Two lower chambers of the heart are known as Ventricles.
- Heartbeat: – in our daily life we notice heartbeat is very important. How it’s done? Our heart is made with muscles when it contracts and relaxes it creates a pump to push the blood. To measure and feel the heartbeat doctors use a special device called a stethoscope.
Excretion in Animals: -
In chapter 10, class 7 Science, we study how carbon dioxide is excreted from our body. As we know, carbon dioxide is a material for our body, like other waste materials like undigested food. When our body cells function, they release some waste materials that are toxic to our bodies. So, it is necessary to remove it from our bodies. This process is called excretion. The part involved in this process is called the excretory system.
Excretory system in Humans: –
The kidney is the most important organ in the excretory system. Capillaries attach to the kidney. Blood reaches the kidney, which contains good and bad materials. Good materials are consumed and returned to the body, and waste materials mix with water and are excreted in the form of urine. Urine goes to the urinary bladder through the ureters and exits from the urethra.
The kidneys, ureters, bladder, and urethra are part of the excretory system. A healthy human urine contains 95% water, 2.5% urea, and 2.5% other products.
Transport of water and minerals in Plants
Animals’ bodies require the transport of different materials like water, oxygen, and other nutrients, and plants have their own transport systems.
As we know, plants’ roots absorb water from the soil. Now, the question is raised: How does this water reach the leaves and other parts of plants? Just as a plant leaf makes food, how does this water reach different parts of the plant? The common answer to both questions is that this system is done in a vessel-like structure. In plants, two types of vessels are found. These vessels are made up of tissues.
Xylem: – it carries water and nutrients from roots and transports them to the leaf and other parts of the plant.
Phloem: – it carries food from the leaf and transports it to other parts of plants.
