Question

give me answer please

Answer 1

a. Interdependency is when several things are reliant upon each other to function. For example, in a car, the engine and battery are interdependent; as the motor charges the battery, the battery sparks the engine.

In the human body, the respiratory, circulatory, digestive, and excretory systems are interdependent. The respiratory system provides necessary oxygen to the rest of the systems that they cannot get on their own. This keeps the cells alive.

b. Blood is important for regulation of the body’s pH, temperature, osmotic pressure, the circulation of nutrients and removal of waste, the distribution of hormones from endocrine glands, and the elimination of excess heat; it also contains components for blood clotting. Blood is made of of several components, including red blood cells, white blood cells, platelets, and the plasma, which contains coagulation factors and serum.

The Role of Blood in the Body

Blood, like the human blood illustrated in Figure 1 is important for regulation of the body’s systems and homeostasis. Blood helps maintain homeostasis by stabilizing pH, temperature, osmotic pressure, and by eliminating excess heat. Blood supports growth by distributing nutrients and hormones, and by removing waste. Red blood cells contain hemoglobin, which binds oxygen. These cells deliver oxygen to the cells and remove carbon dioxide.

Blood plays a protective role by transporting clotting factors and platelets to prevent blood loss after injury. Blood also transports the disease-fighting agents white blood cells to sites of infection. These cells—including neutrophils, monocytes, lymphocytes, eosinophils, and basophils—are involved in the immune response.

c. Iron plays an important role in our body, iron is an important component of hemoglobin. It helps to the red blood cells to carry oxygen from lungs to the whole body. ... So, donating blood iron levels are decreased and it helps to reduce heart and liver problems.
