Question

What are the components of human transport?

Answer 1

Components of human transport:

1. Heart:

1. Two upper chambers, the left, and right atria, and two inferior chambers, the left, and right ventricles, make up the heart.
2. The human heart's primary role is to circulate blood throughout the body.
3. Blood travels twice via the heart in the human circulatory system, with the pulmonary circuit connecting the heart and lungs while the heart and other organs are connected via a systemic circuit.
4. Systemic circulation is the network of blood vessels that transports oxygen-rich blood to and away from the body's tissues.
5. As opposed to systemic circulation, which occurs between the heart and all other bodily tissues, pulmonary circulation is conducted by a system of blood arteries that establishes a closed circuit between the heart and the lungs.

2. Blood:

1. Blood comprises blood plasma and formed elements.
2. Transportation of oxygen, carbon dioxide, nutrients, hormones, heat, and wastes.

3. Blood vessels:

1. Arteries - carries oxygenated blood away from the heart to the capillaries.
2. Capillaries - These facilitate the exchange of materials with the tissues.
3. Veins - returns deoxygenated blood from the capillaries to the heart.

4. Lymphatic system:

1. It is a network of tissues, vessels, and organs that work together to move lymph back to the bloodstream.
2. Lymph transfers materials from blood to the body cells and vice-versa.
