Which protein fiver provides BOTH strength and flexibility in connective tissue?

collagen fibers

Which muscle tissue is striated, multinucleated, and voluntary

Skeletal

Most complex level of organization

organ system

correct order":

cell → Tissue → Organ → system

Tissue that covers surfaces

Epithelial

Tissue responsible for movement

muscle

Tissue that sends signlas

Nervous

Why bone is connective

Support/bind

Epidermis type

Stratified squamous

Tissue that transports nutrients

connective

Does NOT directly acquire energy

Nervous

Columnar epithelium

Tall cells, nuclei bottom

Basement membrane

Anchors epithelium

Neuron count

1 Trillion

Connective tissue function

Support/transport/protect

bone/cartilage type

supportive

Epidermis feature

Keratin + melanocytes

compact vs spongy bone

Osteons vs Porous

cartilage flexible because

Not mineralized

WBC function

phagocytosis + antibodies

Muscle contraction

Actin + myosin slide

Melanocytes

Epidermis → melanin

UV effect

DNA damage risk

Nerve direction

Dendrite → cell → axon

Skin does NOT

Produce ATP

Neuroglia

Support neurons

Heat response

Vasodilation + sweat

Heat response

vasodilation + sweat

Ruptured kidney affects

multiple tissues

Burns dangerous because

lose protection and balance

Sebum produced by

sebaceous

Ventral cavity

heart + organs

heart cavity

Thoracic

Fertilization location

pelvic

Breathing regulation

negative feedback

Homeostasis

Stable internal state

vasodilation

Release heat

Exocrine glands

Epithelial

Incorrect pair

Feathers-mammals

Organ role

regulate balance

Feedback difference

Negative / Positive

heat/lungs cavity

Ventral

Dermis → epidermis

Hair/glands

Lactation

Amplifies Response

Controller

Nervous system

Vessel Lining

simple squamous

4-chamber heart

birds and mammals

Heart murmur

valve leak

Phagocytic WBC

Nutrophils/monocytes

No circulatory system

diffusion

insect blood

no hemoglobin

closed system

Earthworms/vertebrates

Earthworm blood red

Hemoglobin

No system survival

Thin diffusion

correct

Artery/vein naming

“lub-dub-ssshh”

leaky valve

Open vs closed:

Closed=vessels

Exchange occurs:

Capillary

After LV:

Aorta/body

Before LV:

LA → mitral

Before RA:

Vena cava

Artery spurting:

High pressure

Coronary arteries:

Heart muscle

No pulmonary:

Fish

RBC

Biconcave no nucleus

Antibodies

Lymphocytes

Clot start:

Platelets

coreect

Veins toward the heart

Hepatic portal:

Digestive → liver

Pacemaker:

SA node

Fish flow:

Heart→gills→body→heart

Veins return:

Muscle + valves

Reduce disease:

Exercise/diet

NOT cardiovascular:

Diabetes

Hypertension:

More workload

B+

B + Rh

Capillary exchange:

Pressure + osmotic

Planarians:

Diffusion

Open system:

Bathes organs

If BP < osmotic:

Enters capillary

Clot sequence:

Platelets → prothrombin → thrombin → fibrin

Prevent RV backflow:

Pulmonary valve

Blood vs hemolymph:

Not in vessels

Full flow:

Heart→lungs→heart→body→heart

Starts heartbeat:

SA node

Platelets release:
