Introduction The cardiovascular system provides appropriate organ and tissue perfusion at rest and at times of stress by regulation of blood pressure (BP). BP can be expressed as the product of cardiac output (CO) and peripheral resistance. The arterial pressure level at any given time reflects the composite activities of the heart and the peripheral circulation.(Jones, 2004). Nervous system, hormonal and Kidney factors control blood pressure. 1. Nervous System 1.1 CO – Cardiac output CO…

cell bodies, no myelin sheath and slow conduction velocities (9). Both types of fibres aid in thermotransduction (9). Specific thermosensitive channels are believed to be associated with these free nerve endings, working in concert to orchestrate an appropriate response over a wide range of temperatures (8). Once thermally stimulated the thermosensitive channels cause depolarisation of the free sensory nerve endings, generating action potentials, which travel from the periphery to the central…

Vitabrid C¹² is the secret to healthy skin. Using proprietary biotechnology, our DPES system stores, perserves, and delivers 12 continuous hours of antioxidant-rich Vitamin C to your skin. Vitabrid CG, the main component of Vitabrid C¹² exchanges ions with perspiration (NaCl) from sweat glands, skin pores, surface skin wastes, and CO2 in the air and helps Vitamin C absorption by the skin. 7. What differentiates your products from others on the market? What are your key USPs?Our strength comes…

For the purpose of this report we will be focusing mainly on the base level of cells, and those of an animal. Within all organisms we find cells, they form the life blood of their being. Cells contain the blue prints for all life forms known as D.N.A. Cellular structure While complex, cellular structures can also be relatively simplistic in design. Each component of the cell plays a vital role, working together in harmony to provide life. Initially we must look at the cell membrane. The cell…

The type of sauna in which light is created by heat it is known as infrared sauna. Traditionally it is used to warm the air, which results in giving warm to the body. It uses infrared heater which emits light of infrared which is absorbed by the skin. Detoxification: Your skin is the better agency of your body. The subcutaneous fatty band is amid just beneath the skin. An infrared sauna emits application that access into the tissues to a depth of 1.5 inches. Stimulates fat cells, sebaceous…

The Chesapeake Bay’s water quality has been deteriorating over the recent years. Some reasons for the decrease in quality are agriculture, chemical contaminates, and sediment. Agriculture has caused problems for the Bay due to the use of fertilizer. When it rains, the excess nutrients run off into the waterways that lead to the Bay. These excess nutrients include nitrogen and phosphorus. When these nutrients get into the Bay, it causes an algae bloom. The algae bloom blocks any light from…

Biomphalaria glabrata is a freshwater snail that originates from Central and South America. The NMRI strain of Biomphalaria glabrata exhibits albinism. The snails’ albinism makes them transparent, which provides the opportunity to observe their circulatory anatomy and physiology. They lay eggs in masses, with 2-30 eggs per mass. The eggs go through several developmental stages. First, they are fertilized. Each egg contains a single embryo, which then begins to grow. Each embryo measures…

create an artificial skin that has an ability to flex and heal just like actual skin. She did this by connecting micro structured resistive pressure sensors, flexible printed organic electronic circuits, and nerve cells containing light activated ion channels. The pressure sensors are made out of carbon nanotube-elastomer composite shaped into micro pyramidal structures that are covered on top of a surface. The sensors will respond according to programed pressure. Bao in the past had made very…

CELL SIGNALING AND CELL TRANSDUCTION INTRODUCTION: In this lecture, we will study about cell signaling and signal transduction. Each cell in a multicellular animal is bombarded with chemical signals that are made by other cells and this is how communication occurs at cells level by different signaling molecule. Signals that regulate cell metabolism, alter or maintain its differentiated state, determine whether it should divide, and dictate whether it will live or die. The word “signals” in…

Etiopathogenesis Crohn’s has a couple of genes that contributes to its existence. The most know gene is the NOD2/CARD15 “nucleotide-binding oligomerization domain containing 2” that is located on chromosome 16.This chromosomes main function is to help the body attack foreign invaders, it identifies the virus or bacteria and initiates the auto immune system to respond to the invasion. Mutations to this chromosome can increase the chances for a person to get Crohn’s disease, more than 40…
