Lymphatic system definition and function

• Collaboration of organs, tissues (nodes), thinwalled vessels, and fluid

• Function: To maintain fluid balance and contribute to immune system

Organs of lymphatic system

Adenoids tonsils spleen and thymus

Lymph nodes

:filter lymphatic fluid and remove bacteria and foreign objects while making disease fighting cells

Digestive system function

• System where food travels through body and is digested or broken down, almost all of it is in abdominal cavity

1st step of digestive system

1. Food enters mouth and is broken down

2nd step of digestive system

food passes from oropharynx to esophagus, where its transported to stomach

stomach

1. Hollow organ that has acidic juices that begin to break food down

small intestine 3 parts and def

1. 3 parts (duodenum, jejunum, ileum) receives stomach food and continues to break it down, nutrients absorbed through walls

large intestine/colon

removes water from waste, anything not absorbed is secreted

other helpful organs for digestion

• Liver:produces bile that goes to small intestine for absorption, detoxes

• Gall bladder:storage for bile

• Pancreas:Secretes juice to help break down

• Spleen: Acts as blood filtration system

• Appendix: don't know what it does, causes appendicitis

Integumentary system

• Functions include protection, water balance, temperature regulation, excretion and shock absorption.

Epidermis

outermost layer, 4 layers within including outer layer of dead skin cells, pigment granules and living cells are in lower layers, palm and soles of feet have 5 layers. No blood vessels or nerves

dermis

• blood vessels, nerves, sebaceous and sweat glands, hair follicles. Also has specialized nerve endings, second layer of skin

subcutaneus/fatty layer

layer of fat+soft tissue, final layer

Endocrine system

• System of glands that produce hormones that help regulate body activities and function

Pancreas

• : Key organ, creates insulin, which is important for glucose levels

adrenal gland

• produces epinephrine and norepinephrine, which engage sympathetic nervous system

Renal system

regulate fluid levels, filter chemicals, and adjust ph level

Kidneys

principal organs, filter urea from blood+regulate fluid levels in body

bladder

holds urine

ureters

connect kidneys and bladder

urethra

where urine is secreted

Testes

•  Produce sperm, housed outside of body in scrotum, connected to penis through epididymis 

Penus

secretes sperm, male reproductive organ

Ovaries

develop/release ova

uterus

contains fetus

vagina

female reproductive organ
