functions are regulated by the autonomic nervous system‚ or involuntary‚ meaning that we do not consciously have to contemplate digestion for digestion to occur. With this being stated‚ it would make sense that almost the entire gastrointestinal tract is made up of smooth muscle. Smooth muscle is very distinctive from the other types of muscle in the body due to the fact that it is not controlled consciously‚ but unconsciously regulated by the autonomic nervous system through the release of neurotransmitters

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

We are able to visualize‚ feel‚ smell‚ and hear the world around us due to a system called the sensory system. All around the surface of our body we have detectors that are known as receptors. These receptors‚ in the form of cells‚ are specialized to capture specific forms of energy- whether heat‚ light‚ chemical‚ or mechanical (1). The environmental cues that are detected by our receptors on the surface of our body are then transformed into electrical signals‚ or nerve impulses‚ that can be sent

different function. This includes the brain stem which connects to the spinal chord. The brains stem helps to perform basic functions for humans like heart rate‚ breathing‚ digesting food‚ and for sleeping. You can locate the brainstem below the limbic system. The Brainstem contains the pons and medulla. The pons is above the medulla and helps to perform motor control like sounds are transferred from the ear to the brain through the pons. It also helps with your consciousness and sleep. The pons is linked
