Organs Flashcards
(20 cards)
What are the 6 main organs
Heart, Brain, Lungs, Liver, Digestive system and the Spleen.
What is the Brain
The brain is an organ made up of white and grey matter which is made up of neurons. It is not a muscle because it is unable to contract and dilate.
What is the voice box
It is the Larynx. A muscular organ at the front of the neck above the trachea.
Lungs are
A pair of organs that inhale O2 and exhale CO2. They are not a muscle but the diaphram is.
The nervous system has 8 main parts to it. What are they called
Brain, Sight, Smell, Hearing, Balance, Taste, Spinal Cord, Touch.
What is the heart
A muscular organ that pumps newly oxygenated blood throughout the body.
The liver can do what
It has a number of functions. One of them is absorbs nutrients, detoxifies harmful substances and produces bile. It is the largest gland in the body.
What is a function of the stomach
Gastric juice and muscle contractions begin to churning the movement of food that’s been consumed which breaks it down.
Name all the organs in the body(16 parts)
Brain, Voice box, Lungs, Heart, Spleen, Kidneys, Large intestine, Small intestine, Skin, Bladder, Liver, Stomach, Gall bladder, Pancreas, Female/Male genitals, Appendix.
Gall bladder’s function is what
It stores bile produced by the liver and also produces a high concentration of bile by absorption of water through the walls of the gall bladder. It release bile on contraction through the bile ducts to the duodenum.
Pancreas functions are what
The Pancreas is both an exocrine and endoncrine gland. The function of the excocrine pancreas is to produce pancreatic juices that digest carbohydrates, proteins and fats.This juice pours along a duct into the first part of the small intestine. The endorcine pancreas secretes the hormones insulin and glucagon which control blood sugar levels.
Female Genital
Female: Cervix- neck of the uterus
Uterus- Hollow muscular pear-shaped organ which lies between the bladder and rectum.
Ovaries-attached to the upper part of uterus. Glands that produce sex hormones and the ova.
Uterine tubes-(fallopian tubes) about 10cm long extend from both sides of the uterus.
Male Genital
Male: Scrotum- is a pouch of skin containing two compartments each with one testis, one epididymis and the end of a spermatic cord.
Testes- reproductive glands equivalent of the ovaries.
Urethra- a pathway for urine and semen to be excreted.
What is the Appendix
A small closed tube about the size of your finger. It attaches to the beginning of your large intestine open at one end and closed at the other. It doesn’t really have a main purpose.
What is Appendicitis
Appendicitis can occur with a bacteria infection or when a blockage prevents material moving in and out of the appendix causing it swell and become painful and inflamed. It requires surgery otherwise it will eventually rupture causing a dangerous bacteria infection in the bloodstream called peritonitis.
What and where is the Spleen
Largest Lymph organ and acts as a store for some types of lymphocyte and also as a major site for filtering blood.Location- abdominal cavity between the fundus of the stomach and the diaphragm.
What is the function of the Kidneys
They are located on either side of the spinal column in the upper abdominal cavity. Their functions are filtering waste products from the blood, the waste is excreted along with excess water as urine.
Large and Small intestines functions
Small intestine: Continues from the stomach the chemical breakdown and isthe main site for absorption resulting in nutrients into the bloodstream.
Large intestine:the final part of the digestive tract which is in 3 parts Caecum, Colon and rectum.
It changes liquid digestive waste products from small intestine into a more solid form that the body excretes as faeces.
The Bladder does what
The bladder opens into the urethra at it’s lowest point of the neck. It is a muscular sack that when contracts releases fluid from the bladder. Awareness of a comfort break is usually 300-400ml. The total capacity of the bladder is rarely more than 600mls.
List a few purposes of the skin
Temperature regulation protects against extreme hot and cold. i.e sweat glands and subcutaneous fat layer for warmth
Water resistant protects the internal parts from external water i.e rain, bath etc
Protection internally against bacteria, infections etc
Production of vitamin D with the sun.
Sense of Touch which could prevent burns, cuts also healing properties such as body contact hand holding etc
