excretory system includes the kidney and its functional unit‚ the nephron. The excretory activity of the kidney is modulated by specialized hormones that regulate the amount of absorption within the nephron. Kidneys 1 ). They are bean-shaped organs located on either side of the backbone at about the level of the stomach and liver. Blood enters the kidneys through renal arteries and leaves throughrenal veins. Tubes called ureters carry waste products from the kidneys to theurinary bladder for storage

P4 – Explain the role of the kidney in the homeostatic control of fluid balance Homeostasis is how our body works to keep the internal environment constant. The kidneys play a role in the control of fluid balance. For this assignment I will be discussing the gross anatomy of the renal system and the kidney. Renal System The renal system is a group of organs that work together to produce‚ store‚ and release urine. It consists of 2 kidneys‚ ureters‚ the urinary bladder‚ urethra and renal vessels which

to humans to fish‚ maintaining homeostasis through regulating temperature‚ nutrients‚ gas-exchange‚ and hydration is key to survival. Most of these processes are performed regardless of outside environment (such as breathing). However‚ the ways other processes perform are based entirely on what the system (body) of an organism is encountering outside the system. It is extremely important that an organism respond to changes in the environment to maintain homeostasis‚ or illness and death will occur

composition of extracellular and intracellular fluids is vital to life. List and briefly describe the kinds of homeostasis involved. In males and females‚ intracellular fluid has a greater proportion of total body water than does extracellular fluid. Give-and-take between the ICF and the ECF happens across plasma membranes by osmosis‚ diffusion‚ and carrier-mediated transport. The kinds of homeostasis involved are fluid Balance‚ electrolyte Balance‚ and Acid–Base Balance. Fluid balance is when the quantity

WEEK 1: AN INTRODUCTION TO HUMAN ANATOMY & PHYSIOLOGY 1. Define the terms anatomy and physiology‚ and explain their relationship using an example of a human structure with its corresponding function. Anatomy: The branch of science concerned with the bodily structure of humans‚ animals‚ and other organisms‚ esp. as revealed by dissection. Physiology: The branch of biology that deals with the normal functions of living organisms and their parts. Anatomy and physiology are connected in

Physiology is the study of the function of body parts and the body as a whole. The kidneys remove wastes and water from the blood. 2. List‚ in order from least to most complex‚ the levels of structural organization‚ discuss the relationship between the levels‚ and name an example at each level. - Atom- is the smallest

All this result the liver to die because it doesn’t get appropriate amount of blood to survive. * Kidneys: Alcohol can damage the kidneys too. * Stomach: Alcohol use causes irritation in the stomach by increasing the amount of the HCl that result in damaging the lining of the stomach. * Heart: Drinking alcohol every day weakens the muscles of the heart

body that must be eliminated to maintain homeostasis. The urinary system is important for keeping the internal environment of the body clean. This particular system maintains proper homeostasis of water‚ salts and nitrogenous wastes (Iqba‚ 2010). There are four major organs that make up the Urinary system. The four major organs are the kidneys‚ ureters‚ urinary bladder‚ and the urethra. The first organ within the urinary system is the kidney. The kidney is considered as the major organ of the entire
