What is the function of blood Class 10?

1. Blood helps in absorption of digested part of the food and transports it to all cells of the body. 2. It helps in transportation of oxygen from lungs to cells and transportation of carbon dioxide produced by cells to lungs.

How do blood cells work?

The main job of red blood cells, or erythrocytes, is to carry oxygen from the lungs to the body tissues and carbon dioxide as a waste product, away from the tissues and back to the lungs. Hemoglobin (Hgb) is an important protein in the red blood cells that carries oxygen from the lungs to all parts of our body.

What is the role of blood in respiration?

When you breathe out, your blood carries carbon dioxide and other waste out of the body. Other components that work with the lungs and blood vessels include: Alveoli: Tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place.

What is blood in circulatory system?

Blood is a fluid consisting of plasma, red blood cells, white blood cells, and platelets that is circulated by the heart through the vertebrate vascular system, carrying oxygen and nutrients to and waste materials away from all body tissues.

What do red blood cells do?

What do red blood cells do? Red blood cells are responsible for transporting oxygen from your lungs to your body’s tissues. Your tissues produce energy with the oxygen and release a waste, identified as carbon dioxide.

The specific functions of blood also include defense, distribution of heat, and maintenance of homeostasis. Nutrients from the foods you eat are absorbed in the digestive tract.

How does blood help maintain the chemical balance of the body?

Blood also helps to maintain the chemical balance of the body. Proteins and other compounds in blood act as buffers, which help to regulate the pH of body tissues. Blood also helps to regulate the water content of body cells.

How are nutrients absorbed and transported in the blood?

The digested nutrients such as glucose, vitamins, minerals, and proteins are absorbed into the blood through the capillaries in the villi lining the small intestine. The hormones secreted by the endocrine glands are also transported by the blood to different organs and tissues.

What stimulates the production of blood cells in the body?

Certain chemical messengers regulate the production of blood cells. For instance, the hormone erythropoietin, which is produced in the kidneys, promotes the production of red blood cells. And cytokines stimulate the production of white blood cells.
