The skeletal system is absolutely dependent on the integumentary system (the skin) for the calcium that keeps the bones hard and strong. It is activated elsewhere, and (among its other roles) it regulates the carrier system that absorbs calcium from ingested foods into the blood.

The musculoskeletal and integumentary systems account for most of the tissue mass in healthy humans: the skin, muscle, and bone account for about 80% of lean body weight [1]. The main functions of the skin are to protect the body from external stressors, maintain temperature, and prevent fluid loss.

As discussed in previous sections, bone, muscle, and skin are living systems and are active metabolically. They are connected, as are all other organs, by the body’s cardiovascular system. This allows bone, muscle, and skin to respond to hormones and growth factors produced by other tissues.

Musculo-skeletal system gives support to the body andhelps it to move while integumentary syste. protection tothe musculo-skeletal by providing a protective covering. Musculo-skeletal system excretes sweat, thus providing pathway to the integumentary system in. absorbing oxygen.

The integumentary system is an organ system consisting of the skin, hair, nails, and exocrine glands.

The upper muscle in the stomach relaxes to allow food to enter, while the lower muscles mix food particles with stomach acid and enzymes. The digested food moves from the stomach to the intestines by peristalsis. From here, more muscles contract to pass the food out of the body as stool.

The epidermis of thick skin has five layers: stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.

Skin has three layers:

• The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone.
• The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands.
• The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.

Throughout your life, your skin will change constantly, for better or worse. In fact, your skin will regenerate itself approximately every 27 days. Proper skin care is essential to maintaining the health and vitality of this protective organ.

Thin Skin. Thin skin covers most of the body except for the palms of the hands and the soles of the feet. It has a relatively thin epidermis and contains hair follicles, sweat glands, and sebaceous glands.

Include plenty of fruits and vegetables, whole grains, and proteins. Vitamin E, found in foods such as almonds and avocados, can also support skin health. The fats in these foods may help to keep the skin supple. Drinking enough water helps to keep the skin hydrated.
