The lymphatic system is a vascular network of tubules and ducts that collect, filter and return lymph to blood circulation. Lymph is a clear fluid that comes from blood plasma, which exits blood vessels at capillary beds. This fluid becomes the interstitial fluid that surrounds cells. Lymph contains water, proteins, salts, lipids, white blood cells, […]
The skeletal system is the internal framework of the body which provides support and protects the soft organs of the body. The skeletal system is the collection of bones, cartilage, ligaments, and tendons and account for 20% body weight. The skeleton is the structure that gives us our shape and offers a supportive framework for […]
The Human body consists of at least 200 distinct types of cells. These cells contain essentially the same internal structures yet they vary enormously in shape, size, and functions. The different types of cells are not randomly distributed throughout the body; rather they occur in organized layers, a level of an organization referred to as […]
The gastrointestinal system is also known as the digestive system. It is a collective name of the alimentary canal and accessory organs. The alimentary canal forms a continuous tube that is open to the outside environment at both ends. The organs of the alimentary canal are the mouth, pharynx, esophagus, stomach, small intestine, and large […]
The endocrine system helps to perform several body processes by the function of hormones including respiration, metabolism, sexual development, movement, sensory perception, reproduction, growth, etc.”Endo” means “inside” and “crine” means” to secrete “ The fundamental functions of the endocrine system are long-distance intercellular communication, coordination, and maintain hemostasis. A hormone is formed in one organ […]
The cardiovascular system is the transport system of our body in which cardio refers to heart and vascular refers to blood vessels. The basic purpose of the cardiovascular system is to circulate the blood to the cell from cells in the body in order to transport nutrients and remove waste. Hence it is also known […]
Embryology is the study of the origin and the development of embryo till maturation. In this branch of human anatomy we investigate the molecular, cellular, and structural factors which contribute to the formation of an organism, it is also called as developmental anatomy. The study of embryo development helps us to gain knowledge for creating […]
The skin is made up of three major layers: Epidermis – It is made up of closely packed epithelial cells. Dermis – It is made up of dense, irregular connective tissue that includes blood vessels, hair follicles, sweat glands, and other structures. Hypodermis – It is composed mainly of loose connective and fatty tissues. Epidermis […]
Skin is the soft external surface covering of the human body. It is the largest organ of the body. The skin is a connective tissue that consists of cells, fibers, and an extracellular matrix. It is the foundation of the integumentary system which made up of different tissues that are joined to perform a specific […]
The human body has a collective number of biological systems which carry out the specific functions that are necessary to everyday living of human body. The group of organs and tissue form the body system that perform various functions of human body. Some organs may serve more than one function of different systems and some […]
