Study Notes
Transport in Mammals
Overview
- Transport in mammals refers to the movement of substances, such as oxygen, nutrients, and waste products, throughout the body.
- It is essential for maintaining homeostasis, regulating body functions, and supporting overall health.
Types of Transport
- Blood transport: the movement of substances through the bloodstream, facilitated by the heart, blood vessels, and red blood cells.
- Lymphatic transport: the movement of immune cells, proteins, and waste products through the lymphatic system.
- Nerve transport: the transmission of electrical signals through the nervous system.
Blood Transport
- Circulatory system: a network of organs and vessels that transport blood throughout the body.
- Heart: a muscular organ that pumps blood throughout the body.
- Arteries: blood vessels that carry oxygenated blood away from the heart.
- Veins: blood vessels that carry deoxygenated blood back to the heart.
- Capillaries: tiny blood vessels where oxygen and nutrients are exchanged for waste products.
Blood Components
- Red blood cells (RBCs): carry oxygen from the lungs to the body's tissues.
- White blood cells (WBCs): part of the immune system, fighting infection and disease.
- Platelets: involve in blood clotting, preventing excessive bleeding.
Lymphatic Transport
- Lymphatic vessels: a network of vessels that transport lymph, a clear fluid containing immune cells and waste products.
- Lymph nodes: small, bean-shaped organs that filter lymph and trap pathogens.
- Lymphatic organs: include the spleen, thymus, and lymphoid tissues.
Regulation of Transport
- Hormones: chemical messengers that regulate blood pressure, blood sugar levels, and other bodily functions.
- Nervous system: controls heart rate, blood vessel diameter, and other aspects of transport through electrical signals.
Importance of Transport
- Oxygen delivery: essential for cellular respiration and energy production.
- Waste removal: prevents toxic buildup and maintains cellular health.
- Regulation of body temperature: helps maintain homeostasis.
- Supports immune function: enables the immune system to respond to pathogens and disease.
