Muscle tissue is responsible for generating force and producing movement in the body. Skeletal muscles, attached to bones by tendons, enable voluntary movements such as walking and lifting objects. Smooth muscles found in internal organs help with involuntary processes like ...

The primary function of blood is to transport oxygen, nutrients, hormones, and waste products throughout the body. It also plays a crucial role in maintaining homeostasis, regulating body temperature, and defending against infections through its white blood cells.

Efficient blood circulation ensures the delivery of oxygen and nutrients to all cells while removing waste products. This process supports cellular metabolism, energy production, and overall physiological functions, contributing to the body’s health and homeostasis.

Blood carries oxygen and nutrients to all cells while collecting waste products such as carbon dioxide and metabolic by-products. These wastes are transported to organs like the liver and kidneys for disposal.

Mitochondria, which are organelles responsible for producing energy in cells, utilize oxygen during cellular respiration. Therefore, the oxygen transported by the blood to body cells is essential for mitochondrial function and energy production.
