composed of complicated and intricate systems that work together to keep us alive and able to move and process the things we find to be simple such as breathing or blinking. There are 11 systems in our body‚ each in charge of something different and supplying support to the other. Those 11 systems are the‚ nervous‚ skeletal‚ muscular‚ circulatory‚ respiratory‚ digestive‚ endocrine‚ reproductive‚ excretory‚ integumentary and immune systems. I will address every system in the human body as well as provide

Renal system The renal system consists of two kidneys‚ two ureters which come out of the kindeys and a single bladder which collects the urine before it goes into the urethra. It also involves the sphincter muscle which is located just below the bladder and its purpose is to control the flow of urine. The kidneys have renal veins which take the blood from the kidneys into the main vein in the body which is known as the vena cava‚ they also have short renal arteries which come out of the main vein

Body Systems There are 10 body systems‚ one of them is the Integumentary (skin). It is composed of hair‚ skin‚ nails‚ sense receptions and oil glands. Its functionis to protect from outside‚ to regulate the body temperature‚ to make synthesis of hormones & chemicals and is used as a sense organ. Another one is the Skeletal System (bones). It is made of about 206 bones‚ that are divided in tho categories: axial bones (in the body by itself) and apendicular bones (arms & legs). We have Joints too

Organ Systems Project (Digestive‚ Excretory‚ Circulatory‚ Reproductive‚ Nervous) There is an enormous variety of life on our planet Earth ranging from simple cell bacteria to complex multicellular animals. Animals are creatures in the kingdom Animilia‚ one of the kingdoms in Whitakers 5 kingdom system. Their bodies consist of 555tanimal eukaryotic cells. Meaning their cell or cells contain a nucleus‚ are surrounded by a cell membrane (phospholipid bilayer) and can self-reproduce in a free

Lab 28B: Endocrine System Physiology Computer Simulation Introduction The endocrine system is the second greatest control system of the body and has many effects on the tissues and organs. The thyroid gland‚ which is a part of the endocrine system‚ releases a hormone that maintains metabolism. This hormone is thyroxine. Thyroxine production is controlled by thyroid stimulating hormone‚ which is released by the pituitary gland. TSH stimulates the thyroid gland to produce thyroxine. In

Human Science – CHAPTER 1 1. Which Organ system maintains a relatively slow-acting degree of control over most bodily functions? Endocrine System (hormones act in minutes to hours‚ in contrast to nerve impulses‚ which act in fractions of a second). 2. The esophagus and the trachea run side-by-side through the thorax. In which systems are these organs found? The esophagus belongs to the digestive system‚ and the trachea belongs to the respiratory system. (The esophagus carries food to the stomach
