Tissues

cells of similar type that work together form tissue.

4 kinds:

epithelial

lives surfaces inside and outside of the body

important in forming glands( cluster of cells that secrete something) and ducts

# of layers, shape of cells

1 layer- simple epithelium

2 or more layers- stratified epithelium

Shapes

squamous- flat, irregular shape, like fried egg

form linings

simple or stratified

protect against abrasions

cuboidal- cube-shaped

secretion/ glands

usually in simple layer\glands

columnar- column-shaped cell

absorption

connective

connects tissues together, other body parts, protection, support, cushioning of other tissues

loose connective tissues- a gel-like network of proteins and cells that support tissues above it.

dense connective tissue- strap like → ligaments; bone to bone, or tendons; muscle to bone

cartilage- flexible but rigid

bone- harder, mineralized

stores calcium

produces all blood cells and cells of the immune system

blood- liquid connective tissue (plasma- fluid part)

all the nuterients, wastes, antibodies, hormones, etc. are dissolved and circulated by the blood

adipose- fat storage, energy, hormnones, cushioning and insulation

muscular

responsible for general movement externally

moves things inside our bodies as well

voluntary control

skeletal muscle: voluntary, striated with many nuclei

smooth muscle: involuntary, not striated

cardiac muscle: heart, involuntary, striated, intercalated discs

nervous tissue

important to sensing and responding to our internal/external conditions

spinal cord

everywhere you have a nerve/ feel pain

some organs

brain

emotions and thought

Organs will have 2 or more tissues that work together to do a task.

organs that do a related job (like a body process)form organ systems.

anterior- pigs head end

posterior- tail end

dorsal- pigs back

ventral- belly

midline- down the middle of the body

differences between humans and pigs

urinary system- filtering our blood and removing waste

kidneys- filter blood and produce urine from the blood waste

ureters- tubes that carry urine from the kidneys to the bladder

bladder- a muscular sac that stores and expels of the urine.

urethra- tube that drains urine from the bladder to outside

different in both sexes

human and pigs!

Sex organs

male reproductive systems

testes- primary sex organ (sperms, hormones)

scrotum

epididymis- sperm is stored/ matured

vasdefferns =carry sperm from the epididymis to the urethra

in males, the urethra is used for dispelling sperm and urine.

in males, the urethra runs through the penis

in pig, find urethra right by umbilical cord. under the skin

female reproductive systems

ovaries- primary sex organ, makes eggs and hormones

uterine/fallopian tubes- carry eggs from ovaries to uterus.

uterus- organ that holds the fetus
