Transport of excretory materials from the tissues to the liver, kidney or the skin for elimination. Distribution of hormones from glands to the target sites.

What is the most important function of the blood?

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 are the 3 types of blood?

Types of blood cells. There are 3 types of blood cells – red blood cells, white blood cells and platelets. Red blood cells (erythrocytes) carry oxygen to all cells in the body.

What are the 7 types of blood cells?

Blood contains many types of cells: white blood cells (monocytes, lymphocytes, neutrophils, eosinophils, basophils, and macrophages), red blood cells (erythrocytes), and platelets. Blood circulates through the body in the arteries and veins.

What are 5 functions of the heart?

It pumps blood throughout your body, controls your heart rate and maintains blood pressure. Your heart is a bit like a house. It has walls, rooms, doors, plumbing and an electrical system. All the parts of your heart work together to keep blood flowing and send nutrients to your other organs.

What are the functions of blood class 7th?

(a) Following are the functions of blood:It carries oxygen and food to all cells of the body.It transports hormones.It transports waste materials to the excretory organs.It maintains fluid balance and body temperature.It protects against diseases.

What are the 5 components of blood?

Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.

Why is my blood so dark?

Deoxygenated blood is darker due to the difference in shape of the red blood cell when oxygen binds to haemoglobin in the blood cell (oxygenated) versus does not bind to it (deoxygenated). Human blood is never blue.

What is blood and its function PDF?

Blood-Blood is a viscous fluid formed of cellular element suspended in plasma.-The cellular element composed of: Erythrocytes (red blood cells), Leucocytes (white blood cells), and Platelets.-Plasma is a viscous, translucent, yellowish fluid composed of water (90%), proteins (7%), organic salts (1%), and organic ...

What is the function of oxygen in the blood?

Red blood cells bring oxygen to the tissues in your body and release carbon dioxide to your lungs for you to exhale. Oxygen turns into energy, which is an essential function to keep your body healthy.

How does blood transport oxygen?

1. Most of all, blood transports oxygen from the lungs to all the tissues by way of hemoglobin that is embedded in the red blood cells. On the way back to the heart and lungs it transports CO2, which is exhaled by the lungs. 2. Nutrients are taken up in the capillaries of the gut, transported via the portal vein into the liver.

Why are antibiotics needed?

Occasionally antibiotics are needed when our immune system is overwhelmed. 5. Hormones and other signaling molecules (e.g. nitric oxide) integrate the function of various organs. As long as all hormones are present and balanced we have energy and all our organs function perfectly.

What happens when blood clotting factors are paired with platelets?

3. Clotting factors in the plasma of the blood together with platelets contained in the blood see to it that any tiny tears or holes are immediately plugged. Blood has a certain blood pressure, so any defect cannot be tolerated or this could lead to a major bleed. It is interesting that coagulation from clotting factors/platelets and fibrinolysis are constantly balancing each other automatically.

What cells contain infection?

Infection is being contained by white blood cells (lymphocytes for viruses, neutrophils for bacteria) on the one hand and antibodies from plasma cells on the other hand. This is quite an effective system to fight infection. Occasionally antibiotics are needed when our immune system is overwhelmed. 5.

Where are nutrients taken up?

Nutrients are taken up in the capillaries of the gut, transported via the portal vein into the liver. Here many metabolic pathways are followed and the nutrients are further transported through the blood to all of the body cells. 3.

What is the defense of the body?

Defense of the body: by producing antibodies that fight germs and get rid of attacking microbes, which cause many diseases.

How does sweating regulate body temperature?

Regulating body temperature: through sweating to moisturize the skin, or by increasing the burning of sugar in the blood in order to generate energy and raise the body temperature.

Is blood a connective tissue?

Why is it important to know your blood type?

Knowing a person’s blood type is essential if they are receiving an organ donation or blood transfusion. Antibodies will attack new blood cells if the blood is the wrong type, leading to life threatening complications. For example, anti-A antibodies will attack cells that have A antigens.

The expected number of red blood cells in a single drop (microliter) of blood is 4.5–6.2 million in males and 4.0–5.2 million in females.

What percentage of blood is white blood cells?

White blood cells, or leukocytes. White blood cells make up less than 1% of blood content, forming vital defenses against disease and infection. The number of white blood cells in a microliter of blood usually ranges from 3,700–10,500. Higher or lower levels of white blood cells can indicate disease.

What is the blood that is absorbed by the intestines?
