Question

The transport function of blood is dependent on what components? The defense function of blood is dependent on what components? The regulatory functions of blood are dependent on what components? (pages \(116-18\) )

Short answer

The transport function of blood depends on red blood cells, plasma, and blood proteins like albumins, globulins, and fibrinogen. The defense function relies on white blood cells and platelets. The regulatory functions are dependent on hormones, electrolytes, and blood proteins.

Step-by-step solution

Transport Function Components

The transport function of blood is responsible for carrying essential nutrients, gases, and waste products throughout the body. The main components involved in this function are: 1. Red blood cells (erythrocytes): Transport oxygen from the lungs to the body's tissues and carbon dioxide from the tissues to the lungs. 2. Plasma: The liquid part of the blood that contains dissolved substances like glucose, amino acids, hormones, and waste products, which are transported to various parts of the body. 3. Blood proteins (albumins, globulins, and fibrinogen): Help in the transport of other molecules and regulate osmotic pressure.

Defense Function Components

The defense function of blood is responsible for protecting the body against foreign agents and disease-causing organisms. The main components involved in this function are: 1. White blood cells (leukocytes): Play a major role in the immune system by defending the body against infection and removing dead or damaged cells. 2. Platelets (thrombocytes): Responsible for blood clotting, which helps to prevent excessive blood loss and protect the body from pathogens entering through wounds

Regulatory Function Components

The regulatory functions of blood are responsible for maintaining the stability of the internal environment of the body. The main components involved in this function are: 1. Hormones: Produced by endocrine glands, these chemical messengers are transported in the blood and regulate various physiological processes in the body. 2. Electrolytes: Blood contains electrolytes (sodium, potassium, calcium, etc.), which help to maintain the balance of fluids and the pH levels within the body. 3. Blood proteins: As mentioned earlier, blood proteins like albumins, globulins, and fibrinogen play a crucial role in regulating osmotic pressure, which helps to maintain proper blood volume and blood pressure. In summary, the transport, defense, and regulatory functions of blood are dependent on various components, including red blood cells, plasma, blood proteins, white blood cells, platelets, hormones, and electrolytes.
